Printed circuit board plug-in connection

Abstract

A printed circuit board plug-in connection is provided for transmitting the highest possible currents between a printed circuit board and an electrical cable, the printed circuit board plug-in connection being manufactured as simply and economically as possible. For this purpose, a plug-in connection having a slotted pin contact is proposed. Said pin contact is arranged in an insulating body and can be inserted directly into a passage contact opening of a printed circuit board in order to establish electrical contact. The insulating body has detent arms, which releasably engage in detent openings of the printed circuit board in a locking manner at the same time. By means of dovetail connections, several insulating bodies can be fastened to each other, i.e., can be cascaded with each other. A strain relief element can also be fastened to an insulating body by means of the dovetail connection in order to provide strain relief for individual conductors of the cable.
